1. The ability to perceive or discriminate visual details with precision far exceeding normal human vision; visual acuity that surpasses standard thresholds.
Usage: technical; primarily used in vision science and psychology

Examples

• The athlete's hyperacuity allowed her to track the ball with remarkable precision.
• Researchers studied hyperacuity in subjects who could detect misalignments smaller than a single pixel.
• Some individuals demonstrate hyperacuity for color discrimination, distinguishing subtle hue differences others cannot perceive.
• The pilot's hyperacuity was an asset in detecting distant objects on the horizon.
• Vision scientists measure hyperacuity using specialized tests that challenge the limits of human perception.
